0805W8F1102T5E 产品概述

0805W8F1102T5E 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,封装为 0805(公制 2012),阻值 11 kΩ,精度 ±1%,额定功率 125 mW,额定工作电压 150 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该产品以稳定的电气特性、适配表面贴装工艺和成本效益高的特性,适用于各种消费电子、工业和通信类电路中对中高精度电阻的需求。

一、主要参数概述

  • 阻值:11 kΩ
  • 精度:±1%
  • 类型:厚膜贴片电阻(非极性)
  • 封装:0805(2.0 mm × 1.25 mm)
  • 额定功率:125 mW
  • 额定工作电压:150 V
  • 温度系数(TCR):±100 ppm/℃(典型值)
  • 工作温度范围:-55℃ ~ +155℃
  • 品牌:UNI-ROYAL(厚声)

注:功率与其它电气性能通常基于厂方标准测试条件(请以厂家数据手册为准)。

二、产品特点

  • 精度高:±1% 精度适合对阻值容差有较高要求的电路,能保证信号路径和偏置网络的稳定性。
  • 温度稳定性良好:±100 ppm/℃ 的温度系数使其在中等温度波动环境下保持较好的阻值稳定性,适用于需要温漂控制的应用场景。
  • 宽工作温度:-55℃ 至 +155℃ 的工作范围覆盖大多数工业级和商用电子产品的环境要求。
  • 兼容 SMD 工艺:标准 0805 封装便于自动化贴装与回流焊接,适合高产能制造。
  • 成本与性能平衡:厚膜工艺在成本控制方面具有优势,适合大批量应用中替代更昂贵的薄膜或金属膜器件。

三、典型应用场景

  • 信号处理与偏置网络:用于放大器偏置、电平设定和滤波网络等对阻值精度有要求的场景。
  • 分压与阻抗匹配:在模拟前端、数模混合电路中担任分压或阻抗设定元件。
  • 消费类电子与工业控制:TV、机顶盒、家电控制板、工业控制器等通用电子设备。
  • 通信与测量设备:用于阻值稳定性和温度漂移有一定要求的计量、通信模块电路。

四、可靠性与使用注意事项

  • 可靠性:厚膜电阻在经过湿热、温度循环和机械冲击测试后,表现出良好的长期稳定性,但实际寿命与使用环境(温度、湿度、过载情况)相关。
  • 功率与散热:125 mW 为额定功率,实际使用中需考虑PCB散热条件、周围器件热源以及环境温度。长时间靠近额定功率工作会加速老化,应留有裕量。
  • 过压保护:额定工作电压为 150 V,请勿超过此值以避免击穿或阻值漂移。
  • 温度因素:在高温工作环境下(接近上限+155℃)可能影响稳定性,建议根据具体应用预留工作裕度。
  • 可靠性验证:在关键/严苛应用中,建议进行样机测试并参照厂方完整数据手册的环境与老化测试结果。

五、安装与焊接建议

  • 贴装:0805 为常见 SMD 尺寸,兼容常规自动贴片机。贴装时应避免过大的机械压力,防止压裂或引起电阻片层破坏。
  • 焊接:本产品兼容常规 SMD 回流焊工艺。建议在焊料类型与回流曲线选择上遵循焊料厂和PCB厂商建议,并参考厂方数据手册的焊接指南。对回流峰值温度、保温时间等参数应合理控制以免影响性能。
  • 清洗与化学品接触:焊后清洗时应避免使用会腐蚀电阻表面涂层或导致吸湿的溶剂。对特别工况请与厂方确认适用的清洗介质。
  • 焊盘设计:合理的焊盘尺寸和过孔设计有助于散热与焊点可靠性。遵循常规 0805 器件的 PCB 布局规范可降低应力集中和热应力影响。

六、订购与包装

  • 包装形式:通常采用卷带(Tape & Reel)包装,便于 SMT 自动化生产线使用。具体卷盘数量及包装规格请以供应商出货信息为准。
  • 合规性:UNI-ROYAL 系列产品普遍符合常见电气元件的安全与环保规范(如 RoHS 等),如需完整合规证书或可靠性报告,请向供货渠道索取厂家数据手册与认证文件。
  • 备件与替换:若需更高精度或不同温漂等级,可咨询供应商是否提供薄膜或更低 TCR 的同系列替代品。

如需该型号的完整技术资料(数据手册、回流曲线、寿命测试报告或样品订购信息),建议联系 UNI-ROYAL 或授权分销商获取官方文档以供设计验证和生产准入。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
